Pump bulbs are manufactured using 2 molds. A component on one of the two molds shifted during production. This resulted in a gradual build of material on the mold, which gradually decreased wall thickness of the pump. This occurred over the course of several weeks, culminating in a period of time (17 September 2022 to 02 December 2022) where pump bulbs were manufactured below the wall thickness specification.
